Abstract: A transponder is formed of a very thin flexible substrate (10) on opposite sides of which are formed first (26) and second (31) series connected halves of a single antenna coil having ends connected to an integrated circuit die (50) mounted to a corner of the substrate. A plurality of bond pads (12a-12e) and programming pads (14a-14e) are also formed on the substrate and operatively connected to couple the antenna coils and the programming pads through the bond pads to the integrated circuit die. Unique configurations and arrangements of a die mounting site (46), bond pads (12a-12e), program pads (14a-14e), and vias (22, 24) through the substrate enable an inexpensive simple construction. Protective laminates (58, 60) on either side of the substrate are bonded to one another around the edges that circumscribe the substrate and also are bonded to one another at interior portions through a slot (20) formed in the substrate. In one embodiment narrow closely spaced coil turns are grouped in a perimetrical area of the substrate, leaving a large area in the center of the substrate free of antenna coil turns. The thin flexible substrate is stiffened in the area of the die and bond site by thin copper stiffener sheets (46, 202, 234) that are laid down as part of the antenna coil forming process.

Abstract: La manière de construire son abri n'a pas tellement évolué. Aujourd'hui nous construisons encore notre maison avec des murs porteurs. Ce système de construction nous donne un espace habitable très rigide et presque sans flexibilité. Nous ne pouvons déplacer une partie de mur ou de plancher sans compromettre la stabilité structurale de la maison. Notre habitation manque de flexibilité, elle n'arrive pas à suivre l'évolution de l'occupant,elle devrait être à l'exemple du corps humain, un ensemble de cellules qui se développent selon le besoin et avec une flexibilité poussée à son maximum. Pour y arriver, je propose donc à madame et monsieur tout le monde, un système de construction hybride, soit une structure indépendante de l'enveloppe du bâtiment, composé d'éléments moyens pouvant être assemblés manuellement. Ce système d'éléments leur permet de construire eux-mêmes leur espace habitable et de pouvoir le modifier au besoin.

Granted: 2002-03-26
Abstract: In a CDMA receiver, an A/D converter over-samples an analog reception baseband signal with a sampling clock a frequency of which is 2n times higher than a chip clock, and converts it into a digital reception baseband signal.  A correlator obtains a correlation value between the digital reception baseband signal and a pilot spreading code which is synchronous with a reception timing.  A phase difference detecting unit obtains a phase difference between the digital reception baseband signal and the reception timing based on the correlation value.  A timing controlling unit changes the reception timing in such a manner as to eliminate the phase difference obtained by the phase difference detecting unit.

Title: Channel selection in an optical tdma network
Inventor: LUCEK JULIAN KAZIMIERZ
IPC: H04B10/50
Filed: 1997-02-14
Granted: 2002-06-25
Abstract: A receiver at a node in an optical network receives an optical clock signal and a OTDM datastream. A detector converts the clock signal to the electrical domain. A variable delay stage applies a selected delay to the clock signal in the electrical domain. A non-linear electro-optic modulator which may be an electro-absorption modulator, receives the OTDM datastream at its optical input. An electrical control input of the modulator is connected to the output of the variable delay stage. The electro-optic modulator outputs an OTDM  channel selected by setting the delay of the variable delay stage. The variable delay stage may comprise a number of logic gates, particularly AND  gates, connected between a pair of microstrip delay lines. The gates are controlled to provide different paths with different corresponding delay times for the clock signal.

Abstract: The threshing cylinder or rotor of a combine harvester is driven by a rotor hydraulic motor. A rotor pump, driven by an internal combustion engine supplies hydraulic fluid to the rotor hydraulic motor to drive the rotor. A variable speed traction drive propels the harvester over the surface of a field to harvest crops. A control system varies the ground speed of the harvester based upon the pressure of hydraulic fluid supplied to the rotor hydraulic motor to maintain a substantially constant crop material feed rate through the threshing cylinder or rotor. The control system can be an electronic system that measures the pressure of hydraulic fluid on the inlet side of the rotor hydraulic motor and varies the ground speed to keep the measured hydraulic fluid pressure substantially constant. A control system can also include a pressure control valve that varies the ground speed to maintain a constant rotor motor inlet hydraulic pressure.
